You need to have a PDF viewer install. Evince is the default pdf viewer. To make sure it is installed(if you are using ubuntu), open the dash and type "terminal" to up the terminal window. In the window type, #whereis evince. This will tell you if evince is install.
By the way, what flavor of ubuntu are you using,e.g, ubuntu with unity, kubuntu, xubuntu or lubuntu?
